File not found and exception during commit of transaction

Question

Hi All,<p></p>
We are using weblogic 8.1 sp5 and oracle 9.2. In a business process (jpd), I am getting this message and exception immediately after publishing a request document(xml) to a channel and goes to the next process node and the process aborts. Any thoughts are appreciated. Please let me know soon.
<p></p>
Thanks in advance!<p></p>

Answer 1

One possible cause of this issue is that your JPD may have some non-transient field(s) which is/are not Serializable. Check for the warnings in the Workshop, that may point you to such fields.
